Nuclear weapons put all our cities at risk.
Now cities are stepping up to ban them.
In July 2017, the UN adopted the Treaty on the Prohibition of Nuclear Weapons, which forbids all activities related to nuclear weapons: testing, building, funding and even threatening to use them. In a little over a year, the Treaty is well on track to getting the 50 States Parties needed to enter into force. But some countries are dragging their feet. In response citizens are speaking up and cities are calling on their governments to support and join the treaty. We call that support the ICAN Cities Appeal.
"Our city/town is deeply concerned about the grave threat that nuclear weapons pose to communities throughout the world. We firmly believe that our residents have the right to live in a world free from this threat. Any use of nuclear weapons, whether deliberate or accidental, would have catastrophic, far-reaching and long-lasting consequences for people and the environment.

Therefore, we warmly welcome the adoption of the Treaty on the Prohibition of Nuclear Weapons by the United Nations in 2017, and we call on our national government to join it without delay."

Can't find your city on the map below? Then reach out to your city council or elected representatives and urge them to endorse the Cities Appeal. This process is different in each city, so get in touch with your local authorities to ask which steps you'll need to take. To help you get started, you will find print versions and translations of the appeal at the bottom of this page and you can always look through the list of ICAN partners in your country.
Get social! All over the world, people are sharing the campaign by sharing pictures and stories of the places they love in their cities. Join them using #ICanSave.
Watch this space. Soon, we'll be sharing some of the experiences of campaigners around the world and how they got their cities on board. A little inspiration goes a long way (and so do tips, tricks and resources!).
Has your city already already called on your government to join the Treaty on the Prohibition of Nuclear Weapons, but is it not on the list? It's possible we may have overlooked it! Let us know
